Abstract
A power grid of renewable sources is stabilized. Inverters for connecting power sources, such as wind turbines, batteries, or photovoltaics, to a grid are used to damp grid oscillations. The damping is distributed to the inverters, but based on measurements for the grid rather than local measurements. The control of the damping is based on grid wide analysis, and the damping is performed proportionately by already existing inverters distributed throughout the grid.
